fix: add expanded portal schema fields to 5 portals (#1511)

Closes #1511. test_portal_registry_schema.py::test_portals_json_uses_expanded_registry_schema
was failing because 5 portals (workshop, archive, chapel, courtyard, gate) were missing
the expanded schema fields.

Added to each:
- portal_type, world_category, environment, access_mode
- readiness_state, telemetry_source, owner
- destination.action_label

All 6 portal tests pass.
